There are apparently people who believe that "homophobia" should be considered a psychological disease. These people should have their heads examined.
In fact, more study should be done on whether the urge to assign pathological status to people who politically with you is itself a pathology.
The term "homophobia" originally came into use by psychologists to refer to people who were in denial about their own homosexuality. Only in recent years has it come into use as a punitive political bullying term wielded against people who simply disagree, on religious or other grounds, with the condition or practice of homosexuality.
But the political and psychological use of the term together provide a nice little way for LGBT advocates to bully their opponents. How nice it is if you could just label people whose political or social positions you dislike as diseased.
This is also the essence of what the Southern Poverty Law Center does with its label of any socially conservative group as a "hate group."
But don't wait for the people who are always complaining about the "politicization of science" to complain about this. That's because the people who complain about the politicization of science are themselves politicized.
